Re: [AD] Ouya controller support

I got my Ouya today, and I’ve checked out your new branch. I’m going to try the joystick out as soon as I get my game back in building/working order.

The Linux Joystick driver pretty much works as it is! It's just a few defines in linux/input.h that are missing. At first I got error EACCES when the driver opened the device but adding <uses-permission android:name="tv.ouya.DIRECT_INPUT_ACCESS"/> to the manifest solved it!

The adb shell has a tool getevent that can be used to examine the device in various ways:

shell@xxxxxxxxxx:/ $ getevent -lp /dev/input/event1

add device 1: /dev/input/event1

name: "OUYA Game Controller"

events:

KEY (0001): BTN_LEFT BTN_RIGHT BTN_MIDDLE BTN_A

BTN_B BTN_C BTN_X BTN_Y

BTN_Z BTN_TL BTN_TR BTN_TL2

BTN_TR2 BTN_SELECT BTN_START BTN_MODE

BTN_THUMBL BTN_THUMBR 013f

The /dev/input/event/* API should work, but perhaps it emits key and joystick events in a range that the new Linux joystick driver is currently ignoring. We're using some heuristics to determine if the input device is a joystick or not but they are not 100% certain. If you could run a tool like evtest, that would be perfect.
